VALVE.

Specification of Letters Patent.

Application filed October 23, 1920. Serial No. 418,912.

be held securely upon its seat in the valve chamber.

I attain these objects by the mechanism shown in the accompanying drawing, in which Fig. 1 is a vertical section of the valve chamber with my auxiliary valve seat and cage in position. Fig. 2 is an elevation of my auxiliary valve seat and cage, and Fig. 3 is a plan of my auxiliary valve.

Similar reference characters indicate similar parts throughout the several views.

In carrying out my invention, I provide an auxiliary valve seat 14 having an annular part 6 that is designed to pass through the annular body 12 and form a perfectly water tight joint between the regular valve seat 7 and the auxiliary valve seat 7 as shown in Fig. 1. To complete the auxiliary valve seat I form cages by means of the standards 5 and 9, connected and supported at 10 and 16, respectively so the liquid that is being forced through the valve may have free access through the port in the part 6, as indicated by the arrows in Figure 1, when the valve 8, has been opened, as indicated by its dotted outlines in Fig. 1.

In the drawings 1 represents an ordinary globe valve body having a partition 13 through it dividing it into two chambers, the one being a receiving chamber, and the other being a discharge chamber, as indicated by the arrows hereinbefore mentioned. 2 represents a packing box cover for covering the opening for the valve stem, through which opening access may be had to the yalve seat; 3 is a packing box cover for packing around the valve rod 17, and 18 and 19 represent packing used to protect the respective joints or openings from the passage of water through them when properly assembled.

A suitable spring, as 11, or its equivalent, is used to hold the auxiliary valve seat 14 firmly upon the seat at the upper end of the cylinder 12 and avert the possibility of water or other liquid that may be contained in the receiving chamber of the valve body, from passing through when the valve 8 is properly seated.

In Fig. 3 I have shown the valve 8 as provided with notches, a, a, in two sides, designed to receive two of the standards 5, to hold the valve from being made to revolve with the valve stem when opening or closing the valve, as one of the several means that may be employed for the purpose.

The collar 1) is placed upon the valve stem I 17 to prevent the stem from moving longitudinally when operating the valve, 4 being the valve actuating lever or hand wheel by means of which the valve is operated.

It is, of course, to be understood that if a valve like that shown at 8, is used, the hub a must be long enough so that the lower-end of the hole for the reception of the stem 17 will be closed, and still the valve may be moved upwardly upon the stem to allow of a full, free passage of liquids through the valve.

While I have shown a plain, fiat seat, at 15, for the valve 8, it is to be understood that any form of valve seat suitable to the purpose, may be used, as, for instance, an inclined seat as shown at the upper end of the member 12, or other desired form.

To assemble the valve as here shown, the valve 8 is passed between two of the standards and then turned to face its seat, with the notches a receiving two of the standards as guides, and the other two standards are far enough apart so the valve may move freely between them. The stem 17 is then screwed into the hub c and the several other parts, as 2, 3,4 and 11 properly placed, after the cage has been properly placed in the valve body 1.

Having thus fully described my invention, what I claim as new in the art, is:

In combination with a stock valve body tight joint With the regular valve seat, a

valve mounted in the upper standards of the ing operated to open and close, a spring for holding the auxiliary valve seat in proper" contact With the regular valve seat, and means for operating the valve for opening and closing it.
